well you will need:
a sewing machine, or
Step 2: Cutting things!
cut your fabric to about two times around your wrist, and then add 1/2 inch. prep your zipper( i took mine from an old purse
Step 3: Assembling things
you are going to want to place the zipper and the stitching one the wrong side of the fabric, so that when you turn it the right way every thing looks cleaner. Now depending on if you are going to sew or use a sewing machine you might want to use pins to keep things in place.
Step 4: More sewing!
now fold the fabric hamburger style and sew the other side to the zipper. Now once that is done you should only have to sew two edges! YAY! anyway sew those edges with a little bit bit of space.
Step 5: Almost done!
now you will fold the fabric again and the ends of the zippers should touch sew this edge and clean things up. now flip it inside out .....
Step 6: Your done!
now go wear it around town putting what ever you want in it!
